Immune-Onc Therapeutics and University of Texas Report a Novel Target for Acute Myeloid Leukemia in Nature
PALO ALTO, Calif. & DALLAS & HOUSTON, October 17, 2018 / Business Wire / -- Immune-Onc Therapeutics, Inc. (“Immune-Onc”), a privately held cancer immunotherapy company dedicated to the discovery and development of novel biologic treatments for cancer patients, announced today the publication of a study in Nature (DOI: 10.1038/s41586-018-0615-z) that provides new insights into immune regulation and the progression of acute myeloid leukemia (AML).
The study, led by The University of Texas Southwestern Medical Center (“UT Southwestern”) and The University of Texas Health Science Center at Houston (“UTHealth”), demonstrated that leukocyte immunoglobulin-like receptor B4 (LILRB4), an immune inhibitory receptor, orchestrates leukemia invasion pathways by creating an immune suppressive microenvironment. Researchers discovered that blocking LILRB4 signaling with antagonistic antibodies can impede AML development in preclinical models, making it a compelling therapeutic target.
“The immune suppressive microenvironment represents the next frontier in the development of novel approaches to treat cancers like acute myeloid leukemia that have a very poor prognosis,” said senior author Dr. Cheng Cheng “Alec” Zhang, Professor of Physiology at UT Southwestern. “Our findings provide new insights into the underlying biological mechanisms that drive immune suppression and tumor infiltration in acute myeloid leukemia.” Dr. Zhang is a Scientific Advisory Board member with Immune-Onc Therapeutics, who also owns stock and has a sponsored research agreement with Immune-Onc Therapeutics.
This publication is an outcome of multi-year research collaborations between UT Southwestern, UTHealth and Immune-Onc, which has exclusive global rights to develop and commercialize novel biotherapeutics stemming from the sponsored research, including product candidates targeting LILRB4. Leveraging these strategic partnerships with UT Southwestern and UTHealth together with the company’s drug development expertise, Immune-Onc aims to bring much needed new medicines to patients with acute myeloid leukemia and other cancers.
“This pioneering study is a significant milestone in what continues to be a fruitful multi-year collaboration,” said Charlene Liao, Ph.D., co-founder and chief executive officer of Immune-Onc Therapeutics, and a co-author of the Nature publication. “We are proud of this discovery and excited to continue advancing our program toward the clinic on behalf of cancer patients.”
“We are enthusiastic about the research and the potential for new treatment approaches in acute myeloid leukemia,” said Dr. Zhiqiang An, Professor of Molecular Medicine, the Robert A. Welch Distinguished University Chair in Chemistry, and Director of the Texas Therapeutics Institute (TTI) at the Brown Foundation Institute of Molecular Medicine for the Prevention of Human Diseases at McGovern Medical School at UTHealth in Houston. “While immune checkpoint blockade therapies have worked in other cancers, the same benefits have not yet been seen in leukemia. Inhibition of LILRB4 signaling may represent a novel treatment strategy for acute myeloid leukemia.”
About Acute Myeloid Leukemia (AML)
AML, the most common acute leukemia (blood and bone marrow cancer) in adults, is characterized by the proliferation of abnormal myeloblasts (a type of white blood cell) in the bone marrow. Approximately 103,000 new cases of acute myeloid leukemia were diagnosed globally in 2016  and 19,520 new cases are expected to be diagnosed in the United States in 2018 . Despite advances in treatment, only about 27 percent of acute myeloid leukemia patients are alive five years after initial diagnosis .
